(01. 137 1 1 valve controlled dispenser for insecticides, or the,

like, which may be mounted in an area to; be sprayed. A particular object is toprovide a dispenser having a mounting that is readily-adapta-.

ble to either concealed connections or open connections. Stated differently, it is an object of the invention to provide a dispensing device of.

this kind. having a universal mounting,

It is aparticuiar object to providea dispensing device of this kind having a pleasing appearance. A further. object or the invention is to provide a dispenser of this kind having an enclosing cover that may be readily removed and may be eliminated where appearance is no factor. A further object is to provide a dispenser of this kind that is readily accessible for servicing. In particular, it is an object to provide a dispenser having enclosed mechanical parts whichare readily accessibleby the removal of a cover, and which cover may be removed by a very simple operation.

Other objects will appear from the descriptio to follow.

In the drawings:

Fig. l is a side elevation of an embodiment of the invention using enclosed connections, with the mounting thereof-shown in section;

Fig. 2 isa transverse vertical section through the mechanism;

Fig. 3 is a bottom view thereof; and

Fig. 4 is a side elevation of the dispensing devicemounted for open connections, the latter being in section.

Referring particularly to Fig. 2, a ceiling or like mounting base is shown at ID. This base may receive an inset connection box II that is enclosed by a cover plate 12 attached to it removably by screws l3. Preferably, the plate I2 is flush with the lower surface of the ceiling [0. This junction box or connection box I I is adapted to receive a line I5 for the conduction of insecticides or whatever is to be dispensed by the mechanism. It is also adapted to contain suitable electrical leads, such as [6 and I7, which are connected with a power source.

As shown in Fig. 1, the insecticide line l5 may pass out through the side of the box ll, if desired. The manne of terminating the ends of the line I5 and the Wires [6 and l! is, per se, immaterial to the present invention. These 2. terminations may. be .1 made in any conventional manner. i i

Asshown in Fig. 4,.thebox l l maybe mounted; below the surface-of. the ceiling Ill, and attached thereto by conventionalmeans. .(notishown); In

this case, the insecticiderline I5 and .lthei wires. l6 and H will lead laterally from: the: junction: box II and be supportedbelow-.:the surfaceof theceiling I0;

Referring more. particularly again to Fig. 2, the: insecticide line l5ileads througha fitting .20 to. be connected tonan elbowmzli with anpintegral strainer that is fastenedpthrough .theside of a, valve body element 22. This, valve bOldy element hasa vertical. bore: extending down.- fromthe top. thereof, and; .aflording elevated, ,valve .1 seat: 2i. A. valve E passage 1 25:. extends; vertically from the. valve. seat zAatoa distributin po n from; which multiple ports 26 radiater These. ports have fittings 21 that. receivenozzles Z8. tnreadedwthereonto. Thus. he devic pr vides multiple nozzlesvthatareiasshown inFie. 3 as comprising four nozzles. directed... at to, each:- other.

The. bore :23 :has a. ,tube .30 fixed therein. This tube-has aplug-tl permanently ntted and held in its top. The plug, 3| hasa; threaded extension 3Zithat passes throughthe top plate lz and re.- ceives suitable 1 nut and washer arrangement 33, whereby the tube,, the; valve body 22, and the various nozzles are supportedirornithe box H.

The, tube, contains a solenoid core, 35. which hasia vertical passage theretl' l'qugh in 1 which .a valve sterr iifiireciprocates. Thevalve, stem carries avalverhead-tl atitslower end, this head. being, cooperable with thevalveseat 24. The p er nd of the va vestemtfi carr es. ahead at thati may sea n a-socketiprovided in the top of the core 35.

The tube 30 passes upwardly through the two leg members of a U-shaped bracket 40. The upper leg member 4! of the bracket 40 is engaged by the top of the plug 3| and receives the threaded projection 32 therethrough. The lower leg member 42 has an opening large enough to receive the tube 36. By this means, the bracket 40 is supported. This bracket receives a magnetic coil 43 that is energized from the two leads [6 and I1. This magnetic coil surrounds two oppositely inserted sleeves, as shown.

The bottom of the valve body 22 is adapted to receive a threaded plug 45. This plug projects from the bottom of the valve housing and is adapted to have a bowl-shaped cover member 46 pass over it, The cover member has suitable 8 openings 47, through which the nozzles 28 project. The upper end of the bowl member may engage the lower surface of the ceiling ID in the mounting shown in Figs. 1 and 2. It is clamped thereagainst by a cap screw 48. Where the arrangement is that shown in Fig. 4, the cap nut 48 will cause the cover 46 to engage the bottom of the valve body, and thereby be clamped stem and lift the valve to an open position. This will permit the insecticide from the line to flow into the bore .23 thence around .the valve seat 24, and out the passage to the several ports .26, whence it .may be dispensed through the four. nozzles 28. When it is desired to stop the dispensing operation, the switch S may be opened. This will deenergize the coil 43, and permit the core to fall, carrying the valve downwardly to its closed position.

When it is necessary to service the valve parts, the cap nut 48 may be removed. This will permit the cover .46 to. be withdrawn from the bottom. When the cover is removed, the entire valve mechanism is readily accessible, The valve mechanism may then be removed by separating the tube 15, disconnecting the wires l6 and I1, loosening the screws I3, andv withdrawing the plate l2. The valve may be quickly disassembled by removing the nut 33 and detaching the union connector 2|]. When the nut 33 is removed, the tube 30, the valve body 22, and the associated parts may be slipped through the bracket 40, andthereby removed from the coil for any servicing that is necessary. Obviously, various nozzles may be applied to the fittings 21. i

It will be seen that a'structure has been provided which is efiicient in operation, easy to service, and pleasing in appearance. Furthermore, it has a'very simple mounting arrangement that is adapted for use with either exposed wiring or concealed wiring and connections.
